SAD-IRON.

Specification of Letters Patent.

Patented May 13, 1913.

Application filed February 8, 1912. Serial No. 676,199.

' ful Improvements in Sad-Irons, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in sad'irons of the kind employing a reservoir for gasolene from which is generated gas by means of which the iron is heated and more particularly to that type of device wherein such reservoir is utilized as the handle of the iron.

It has for its object to provide an improved arrangement of the pipe for conducting the oil from the reservoir-l'iandle to the burner; to provide improved means for shielding the said reservoir from the heat produced in the body of the iron; to provide a device having a readily-removable core; to provide improved means for locking said core in place and also for looking at the same time the core-carrying base to the shell or body portion; and to improve generally the construction and operation of devices of this character.

That which I believe to be new will be pointed out in the claims.

In the drawings, Figure 1 is a side elevation of my improved device; Fig. 2 is a top or plan view of the same; Fig. 3 is a horizontal section taken at line 3-3 of Fig. l; Fig. 4t is a longitudinal, vertical section taken centrally through the device; Fig. 5 is a vertical cross-section taken at line of Fig. l; Fig. 6 is a detail, being a horizontal section taken at line (5-6 of Fig. 4t; and Fig. 7 is a detail, being a section taken at line 7--7 of Fig. 4: and showing the air inlets in the rear end of the shell or body.

Referring to the several figures of the drawings, in which corresponding parts are indicated by like reference characters, 10 indicates the base, the lower face of which 1s,

of course, to be very smooth and highly polished as usual. lhis base is formed hollow and 1ts side walls converge toward each other and meet at its forward end so that the base will have the usual appearance of sadirons generally.

11 indicates a metallic core fitting within the base 10 and conforming to the interior shape of said base. Around its upper edge it is provided with a recess 12 as clearly shown in Figs. 4 and 5. The making of this recess provides a narrow space at the sides and rear of the device, between the vertical walls of the base 10 and the outer face of the core 11, which is adapted to receive the lower edge of the shell or body portion hereinafter described.

13 indicates the shell or body portion just mentioned, which is made of a size and shape to adapt its lower edge to enter the recess 12, said lower edge of the shell or body resting on the bottom of the recess that is formed in the upper edge of the core 11. Being thus seated in this recess it will be held firmly between the vertical walls of the base and the upper portion of the core. It is locked in this position by an inwardly projecting point l l formed at the forward end of the base 10, which enters a suitable opening in the shell or body 13, and at its rear end by a locking lever 15 pivoted at 16 to a short rearwardly extending lug 17 on the upper rear edge of the base 10, said lug being preferably integral with said base. The engaging end of this pivoted lever 15 is adapted to be projected through a slot 15 in the rear wall of the shell or body 13 and thus lock the shell or body at its rear end firmly to the base 10. As will be seen by reference to Fig. f the lever also lies closely over the rear end of the core 11 and thus at the same time aids in holding that core against any possible movement. The shell or body is preferably made of a single piece of sheet metal suitably stamped into the desired shape. l'Vithin the shell or body is located a large tube 18 forming the burner of the device. It is preferably of tubular shape and has openings 19 in its under part for the escape of the burning gas. It is closed at its forward end but open at its rear end and suitably secured at such rear end to the rear wall of the shell or body 13. This rear open end of the tube 1.8 is somewhat enlarged, as shown in Fig. 41, and the shell or body 13, opposite this enlarged rear end of the tube, is provided with air openings 19 of any desired shape and number, through which air may be drawn for mixing with the vapor from the oil drawn from the reservoir as hereinafter described.

20 indicates a plug in the enlarged rear end of the tube 18 which is secured in the rear wall of the shell or body 13, which plug in its forward portion is provided with a small discharge passage 21 that opens at its forward end into the interior of the tube 18 and also communicates with a lateral passage (see Fig. 6) 22 that communicates with the oil supply pipe hereinafter described.

23 indicates a needle-valve adapted to control both passages 21 and 22. The stem of this valve is screw-threaded into the plug 20 and at its outer end is provided with an ordinary head 24.

25 indicates a shield lying in the upper portion of the shell or body 13 and fitting snugly therein. As shown it is arranged between the tube 18 and the upper wall of the shell or body and it may be secured to such shell or body in any desired manner. As shown I secure it by means of a screw 26 passing through the upper wall of the shell or body. At each side of the shell. or body are cut a large number of openings to permit the free admission of air to the interior of the shell or body, and they are so arranged with reference to the shield 25 that the air entering through them will pass above and below such shield and thereby tend to make the shield much more effective in keeping the upper wall of the shell or body, and also the parts hereinafter described are attached thereto, from becoming unduly heated.

28 indicates a bracket suitably secured to the upper wall of the shell or body 13 and raised a considerable height above such shell or body. This bracket furnishes a support for the handle of the iron, said handle con sisting, in the construction shown, of an arcshaped member 29 which is considerably higher at its forward portion than at its rear portion and a long cylindrical portion 30 which is mounted upon and suitably secured to the arc-shaped portion. This por tion 30 constitutes the part that is to be grasped by the hand of the operator and is arranged upon the arc-shaped member 29 so that its forward end is considerably higher than its rear end. This not only makes a conveniently arranged handle, but insures the oil that is to be used in forming the gas for heating the device and which is to be stored in this hollow cylindrical portion 30, always being carried down to the discharge pipe that leads it to the burner. The portion 29 of the handle is preferably made of wood as being a good nonconductor of heat, and, to further insure as much as possible the portion 30 against heating, I insert pieces of asbestos, or si1nilar insulating material, 31 between the bracket 28 and the handle portion 29. It is desirable that the gasolene should pass through a comparatively long pipe before it is discharged into the burner and I have, therefore, so constructed and arranged such pipe as to provide for a large amount thereof being located outside of the shell or body and so disposed with reference to such shell or body as not to present an unsightly appearance. This pipe-indicated by 32is connected to, and communicates with, the

lower rear end of the reservoir-handle 30 immediately over the stem of the valve 23. It is brought down alongside of such stem and then wound in a series of coils 33 around such stem and is then passed through a suitable opening in the upper rear portion of the shell or body 13 above the shield 25, over which it extends, to near the forward end of such shield where it is bent upon itself and brought back to near the rear end of the shell or body. This looped portion of the pipe that lies above the shield is marked 34:. Through a notch 35 (see Fig. 3) in the rear edge of the shield the pipe is passed down and extends forward alongside of and close to the perforated portion of the burner tube 18 and near the forward portion of such burner tube is turned back and its end suitably secured tothe laterally extending nipple on the block 20 (see Fig. 6), which nipple has in it the passage 22 hereinbefore referred to. This last loop of the pipe that extends along each side of the perforated bottom of the burner tube 18 is marked 36. By this construction it will be seen that the supply pipe is made very long and that the portions 32 and 33, which are entirely outside of the shell or body, will be kept comparatively cool, that the loop portion 34 lying as it does above the shield 25 and subjected to the air entering the openings 27 will also be kept comparatively cool although not, of course, to the same extent as the first described portions of the pipe, while the loop 36 of the pipe will be, as is desired, very much heatedto vaporize the oil therein as it passes to the burner through the passages 22 and 21 that are controlled by the needle-valve 23. As clearly seen in Figs. 4 and 6 the burner tube 18, at about the point where it commences to enlarge, is provided interiorly with an an nular wall 37 having a central opening 38 in line with the passage 21 in the plug 20. This forces the mingled air and vapor to pass more uniformly and properly into the burner tube and in effect forms of the enlarged rear end of the tube 18 a mixing chamber. In the upper forward end of the handle-reservoir 30 I form a filling opening Which is normally closed by a hollow screwthreaded plug 39 and which may be, as shown in Fig. 4, itself provided with a second screw-plug 10 which latter may be removed if it is desired to introduce air under pressure into the reservoir.

It is often desirable to have one weight of sad-iron at one time and another weight at another time, and by my construction I provide a device that can be readily and quickly adapted for these difl'erent conditions of use, for, by having a number of different cores of ditferent thicknesses and substituting one for the other the weight of the device as a whole can be materially changed, and as each core will be made so as to extend at its edge portion up to the same height in the base as any other core, and as each core will be provided with the recess 12 it will be seen that the shell or body will in each instance fit properly in place so that the parts can be locked together in the manner described for the core shown without any looseness of fit. These cores, of course, can be rough pieces of cast metal, needing no expensive finishing, and in addition to furnishing the desired amount of weight to the device they very quickly become very much heated from the intense heat of the numerous flames issuing from the openings 19 immediately above the core, and thereby tend to maintain a proper heat in the base itself. WVhen the shell or body is to be separated from the base the lever 15 is turned so as to be disengaged from such shell or body and then the rear portion of the shell or body is to be raised sufficiently to bring it above the rear wall of the base, and then, of course, a slight backward pull will draw the shell or body away from the point 1-1 at the forward end of the base. To again connect the parts the shell or body is moved forward over the base until such point onters the opening, at which time the rear portion of the shell or body can be forced down between the base and the core and then a turning of the lever 15 will again lock the two parts rigidly together.
